It is a warm afternoon. You are supporting a service user at home and you notice something is not right. They seem confused. Their skin feels hot and dry. They are not responding the way they normally would.
You think it might be heatstroke. You need to act and you need to be sure you are doing the right thing.
This guide gives care workers and managers clear, practical steps for recognising and responding to heatstroke in a care setting. It covers what good prevention looks like day to day, how Lyra can support your team in the moment, and what CQC expects care providers to have in place when temperatures rise.
We have also put together two free resources to help your service stay prepared this summer. You will find them linked throughout this article.

Recognising Heatstroke in Vulnerable Adults
Heatstroke is a medical emergency. It happens when the body overheats and can no longer cool itself down. In healthy adults it is serious. In older people, or those with complex health needs, it can become life-threatening very quickly.
The signs are not always obvious. In vulnerable adults, symptoms of heatstroke can look like confusion, a urinary tract infection, or a general deterioration in condition. That is why it is important to consider heatstroke as a possibility on hot days even when you are indoors.
Signs to look for
A body temperature above 40 degrees Celsius, or skin that feels very hot to the touch. Confusion, agitation, or unusual behaviour. Skin that is hot and dry the person is not sweating despite the heat. A rapid, strong pulse. Nausea or vomiting. Slurred speech or difficulty communicating. Unresponsiveness or loss of consciousness.
Not every sign will be present in every case. Trust your instincts. If something feels wrong and the weather is hot, take it seriously.
How heatstroke differs from heat exhaustion
Heat exhaustion comes first. The person will typically be sweating heavily, feeling weak or dizzy, and their skin will be cool, pale, or flushed. They are still conscious and able to communicate. Moving them somewhere cool and encouraging fluids will usually help.
Heatstroke is more serious. The body has stopped sweating. Skin is hot and dry. The person may be confused, unresponsive, or losing consciousness. If you are unsure which you are dealing with, treat it as heatstroke and act immediately.
The free heatstroke poster covers the key differences in a format your whole team can refer to quickly. Download it here.
What to Do Immediately
Call 999 first if the person is unconscious, unresponsive, or deteriorating rapidly.
Heatstroke is a medical emergency. Do not delay calling for help while you attempt to cool the person. Call 999, explain the situation clearly, and follow the operator’s instructions. Your role is to support the person while professional help is on its way.
If the person is conscious and responsive
Move them to a cool environment immediately indoors with a fan or a shaded area outside. Lay them down and raise their legs slightly if possible.
Begin cooling them as quickly as you can. Remove excess clothing. Apply cool water to the skin, particularly the neck, armpits, and groin. A fan directed at wet skin is one of the most effective methods. Do not use ice or very cold water directly on the skin — this can cause blood vessels to contract and slow the cooling process.
Encourage them to sip cool water if they are conscious and able to swallow safely. Do not give fluids if there is any risk of aspiration.
Monitor them continuously. Heatstroke can deteriorate rapidly. If their condition worsens at any point, call 999 immediately.
What not to do
Do not leave the person alone. Do not give them aspirin, paracetamol, alcohol, or caffeine. Do not use a cold bath or shower the shock can cause additional complications in vulnerable adults. Do not assume they will be fine because they seem to improve quickly. Heatstroke always requires medical assessment even when the person appears to recover.
Recording what happened
Note the time you noticed symptoms, the temperature of the environment, the specific symptoms observed, every action taken and when, and the person’s response to each intervention. This record matters for handover to paramedics, for the care plan review, and for any CQC or safeguarding process that follows.
Getting Guidance in the Moment with Lyra
In a difficult moment on shift, you should not have to search through a policy document for answers.
Lyra is QCS’s AI assistant, available through the QCS app. It gives care workers clear, practical guidance on demand from emergency responses like this one to medication queries, safeguarding concerns, and everyday care decisions. You do not need to know exactly which policy applies. You just ask.
If you are unsure whether what you are seeing is heatstroke or something else, unsure of the right next step, or unsure what to tell the ambulance crew when they arrive ask Lyra. It gives you a clear answer based on real QCS guidance, in the moment you need it.
If your service uses QCS, Lyra is already available to your team through the QCS app.

Most heatstroke incidents in care settings are preventable. The care workers who spot the risk early and take practical steps are the ones who stop a warm afternoon becoming a medical emergency.
Know who is most at risk
Some service users are more vulnerable to heat than others. Older adults regulate body temperature less efficiently. People taking certain medications including, diuretics, beta blockers, and antipsychotics, are at higher risk. Those with heart conditions, kidney disease, or limited mobility are also more vulnerable.
Know which service users on your caseload fall into these categories. On hot days, check on them more frequently than usual and note what you observed in the care record.
Make hydration part of every visit
Dehydration is both a cause and an accelerator of heatstroke. Encourage service users to drink water regularly throughout the day, not just when they feel thirsty. Older adults often have a diminished thirst response and may not realise they need fluids until they are already dehydrated.
Offer cool drinks at every visit on hot days. Note in the care record whether the person has been drinking adequately. A simple entry – offered fluids, service user drank well – takes seconds and provides the evidence needed if a concern is raised later.
Check the environment
A south-facing room with no ventilation can reach dangerous temperatures on a hot day. On warm days, check the temperature of the rooms your service users spend time in. Open windows, draw curtains to shade direct sunlight, and use fans where available.
If a service user’s home is consistently too hot during warm weather, flag it to your manager. It is a risk that belongs in the care plan.
Prepare your team before summer arrives
Good care services do not wait for a heatwave to think about heat risk. Managers and owners can use our free heatwave checklist to make sure their service has everything in place, from identifying vulnerable service users to ensuring staff know the emergency steps.
The checklist is free to download and includes the heatstroke poster your team can print and display in the staff room and communal areas.

Heat exhaustion is the earlier stage the person is still sweating, conscious, and responsive, with cool or flushed skin. Moving them somewhere cool and encouraging fluids will usually help. Heatstroke is a medical emergency. The body has stopped sweating, skin is hot and dry, and the person may be confused or unresponsive. If you are ever unsure which you are dealing with, treat it as heatstroke and act immediately.
In care settings this distinction matters because the response is different. Heat exhaustion can often be managed on site with prompt action. Heatstroke always requires emergency medical assessment even if the person appears to recover. Vulnerable adults, particularly older people and those on certain medications, can move from heat exhaustion to heatstroke more rapidly than a healthy adult would, which is why early recognition matters so much. Our free heatstroke poster covers the key signs of each in a format your whole team can refer to quickly. Download it here.

Record the time you first noticed symptoms, the environmental conditions including room temperature if possible, the specific symptoms observed, every action taken and when, and the person’s response to each intervention. Note when you called for help or escalated to your manager.
This record serves multiple purposes. It supports the clinical handover to paramedics or hospital staff, feeds into the care plan review, and provides evidence for any CQC or safeguarding process that follows. Accurate, timely recording is part of safe care, not an afterthought. If your service uses QCS Care Management, care workers can record observations and actions digitally in real time, creating a consistent and accessible evidence trail across every shift.

A hot weather policy should identify service users at higher risk, set out specific monitoring steps for hot days, give clear guidance on recognising heat exhaustion and heatstroke, establish when to escalate and when to call 999, and specify how incidents should be recorded. Staff must be able to find and use it, not just know it exists.
CQC will look for evidence that the policy translates into consistent practice across shifts, not just a document sitting on a system. Review your policy at least annually and update it whenever national guidance changes. QCS Compliance Centre maintains hot weather and environmental risk policies for you, updating them automatically so you never have to monitor guidance changes manually. You can also download our free heatwave checklist to help your team put good practice in place immediately. Get it here.
What CQC Expects from Care Providers
CQC’s Safe key question looks at whether people are protected from avoidable harm. Heat-related risk sits squarely within that expectation. Inspectors will want to see that your service has identified which service users are vulnerable to heat, that staff know what to do in a heat-related emergency, and that environmental risks are monitored and managed.
Under Well-Led, CQC will also look at whether your policies for managing risk in extreme temperatures are current and whether staff can demonstrate they know what those policies say. The gap between having a hot weather policy and staff actually knowing it is one of the things inspectors look for.
What good looks like in practice
A hot weather policy that is current and accessible to all staff. Care plans that identify heat-vulnerable service users and set out specific monitoring steps. Records that show hydration and environmental checks were carried out on hot days. Staff who can speak confidently about what they would do in a heat-related emergency.
Evidence is everything. A care worker who can say clearly, I noticed the room was warm, I offered fluids, I recorded it, and I flagged it to my manager, is demonstrating exactly the kind of consistent, thoughtful practice CQC is looking for.
Keeping your hot weather policies current
QCS Compliance Centre includes health and safety policies covering environmental risk and hot weather care, automatically updated when guidance changes, so your team always has the right documentation in place. Over 7,200 UK care locations rely on QCS to keep their policies current without the administrative burden of monitoring every regulatory update.
